YB-1, a multifunctional DNA- and RNA-binding nucleocytoplasmic protein, is involved in the majority of DNA- and mRNA-dependent events in the cell. It consists of three structurally different domains: its central cold shock domain has the structure of a β-barrel, while the flanking domains are predicted to be intrinsically disordered. Recently, we showed(More)
Drosophila melanogaster is a model organism instrumental for numerous biological studies. The compound eye of this insect consists of some eight hundred individual ommatidia or facets, ca. 15 µm in cross-section. Each ommatidium contains eighteen cells including four cone cells secreting the lens material (cornea). High-resolution imaging of the cornea of(More)
Polypeptide synthesis using either phenylalanine or lysine was initiated on Escherichia coli ribosomes; then the position and conformation of the nascent peptide were monitored by fluorescence techniques. To this end, fluorophores had been attached to the amino terminus of each nascent peptide, and major differences were observed as chain extension(More)
This review is devoted to substantiation of new characteristics for classification of living organisms. The novel view of a role of flexible regions in protein functioning and evolution is suggested. It is based on the newly revealed correlation between the number of loops in elongation factors and the complexity of organisms. This correlation allowed us to(More)
Presented paper is devoted to theoretical modeling and experimental investigation of transferring of initial phase of low frequency oscillations with modulation of carrier oscillations in separate high frequency link from one part of testing link to another. The main goal of this investigation is the determination of influence of phase stability of separate(More)
